Guhathakurta (UCSC) UCSC LBV 0.006 1 Add UCSC Red spectrum (black body temperature ~ 4,500 K, assuming no host extinction) with a distinctive narrow H-alpha emission feature (FWHM ~ 1300 km/s), red-shifted at 260 km/s relative to the host (NGC 718, with spectroscopic redshift z = 0.005781). The (observed) absolute magnitude of the transient is M_r = -13.3, and dereddening by an appropriate amount to match the Na D absorption strength (EW ~ 6 Angstroms), we estimate a temperature of 15,700 K and an absolute magnitude of ~ -16. We consider these properties most similar to a reddened LBV outburst, however it is also consistent with a luminous red nova. We thank the Lick Observatory staff for helping with these target-of-opportunity observations. ATel: 13263 2019TNSCR2287....1S
